Reference Model replaced by S-Function target code generation

If I replace a Referenced Model with a generated S-Function, using the interactive process, I get the expected behaviour for simulation purposes.
However, what I need to do is to generate code for an embedded target (NOT PC) that is based on the ert coder. I can generate the code for the stand-alone model using the ert technique, but it seems like I need a separate mex/tlc combination for target code generateion that would integrate the previously built obj/archive file from the S-Function.
What are the recommended approach to build a model that references these types of S-Functions for target code generation?

Why did you replace the reference model with an S-Function. Best approach is to simply generate code for top model with referenced model. Then you don't need to mess around with S-Functions or TLC.

Thanks for the reply. Original goals were to both provide some hidden model capability, as well as possibly speed up simulation portions. It looks like the "Protected Model" is more in line with the recommended approach. The "Binary" output solution appears to be dependent on setting up a Toolkit to perform the compilation/linking required to create the binary deployment. With our special target, including external libraries, it seems much easier to just use the Code Generator and do the compile/link external.
Yes, Protected Model is the recommended approach to hide model capabilities... however if you allow generating code then you are still exposing model capabilities to users via the resulting C code. Simulation performance with reference models can be sped up by placing the referenced model in Accelerator mode.
